.............years ago, a group of us went deer and blue quail hunting in West Texas each fall on a 20,000 acre lease. Since we were a hundred plus miles from competent medical help, we were all extra careful about everything but particularly rattlesnakes. Some of us took to carrying .410 pistols for the jillions of rattlers and we had no policy of accommodation to the rattlers. See one, kill it! The rattlers had the same policy towards us!
Similarly, Europe, if it wants to save itself, will have to adopt the same policy. Namely.........”if you see a rattlesnake (male, fighting age muslim).........”kill it”!
Deport all others systematically.
Sounds like a plan.
